| 5 | Specify properties of primary function inputs. | Specify Properties of Entry-Point Function Inputs |
| 6 | Generate the MEX function using | codegen |
In this example, you use the codegen function
to generate a MEX function from a MATLAB® file that adds two inputs.
You use the codegen -args option
to specify that both inputs are int16.
In a local writable folder, create a MATLAB file, mcadd.m,
that contains:
function y = mcadd(u,v) %#codegen y = u + v;
Generate a platform-specific MEX function in the current
folder. At the command line, specify that the two input parameters
are int16 using the -args option.
By default, if you do not use the -args option, codegen treats
inputs as real, scalar doubles.
codegen mcadd -args {int16(0), int16(0)}codegen generates a MEX function, mcadd_mex,
in the current folder. codegen also generates
other supporting files in a subfolder called codegen/mex/mcadd.codegen uses
the name of the MATLAB function as the root name for the generated
files and creates a platform-specific extension for the MEX file,
as described in Naming Conventions.
